Publication number: 20210199539Abstract: A test device includes an input side drive part that drives a steering shaft of a steering device, a control part that controls the input side drive part, and a position detecting part that detects an angular position of the steering shaft. The control part restricts a maximum value of a torque of the steering shaft when the angular position reaches an end abutment position. The control part also controls driving of the steering shaft by a position control in which the angular position is used as a controlled variable and a torque control in which the torque is used as a controlled variable. The control part performs the position control when the angular position is outside a first angular range including the end-abutment position and switches the driving of the steering shaft from the position control to the torque control when the angular position reaches within the first angular range.Type: ApplicationFiled: March 12, 2021Publication date: July 1, 2021Applicant: KOKUSAI KEISOKUKI KABUSHIKI KAISHAInventors: Sigeru MATSUMOTO, Hiroshi MIYASHITA, Kazuyoshi TASHIRO, Kazuhiro MURAUCHI, Hiroyuki MIURA, Akihiro YONEKAWA, Kazuki SHINOHARA

Patent number: 10354048Abstract: A control device including a simulation unit to simulate behaviors of a virtual mechanical system, and a drive control unit to control driving of servomotors based on the simulation results, is provided. The virtual mechanical system includes a first drive module, a first main shaft module connected to the first drive module, and a plurality of power transmission subsystems, each of which is connected to the first main shaft module and is associated with one of the servomotors respectively. Each of the power transmission subsystems includes an output module. The servomotor associated with the power transmission subsystem is driven according to a simulated result of input into the output module.Type: GrantFiled: June 2, 2014Date of Patent: July 16, 2019Assignee: KOKUSAI KEISOKUKI KABUSHIKI KAISHAInventors: Sigeru Matsumoto, Hiroshi Miyashita, Kazuyoshi Tashiro, Kazuhiro Murauchi

Patent number: 10253684Abstract: An internal combustion engine control apparatus includes a secondary air supply device having a secondary air supply passage that supplies secondary air pumped by an air pump into an exhaust system of an internal combustion engine and an opening/closing unit that opens and closes the secondary air supply passage. A controller provided in the internal combustion engine control apparatus sets the opening/closing unit in an open condition such that the secondary air is supplied to the secondary air supply passage, and then executes foreign matter removal control in which the opening/closing unit is opened and closed. As a result, foreign matter caught in an ASV during AI control is removed immediately. By implementing OBD after removing the foreign matter, detection of an open sticking abnormality caused by foreign matter caught in the ASV is suppressed.Type: GrantFiled: August 6, 2012Date of Patent: April 9, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shinya Kondo, Ryosuke Tsukamoto, Hironori Kitadani, Jun Aoki, Shinsuke Kiyomiya, Kazuyoshi Tashiro, Satoshi Kawai, Tatsuro Nakata

Patent number: 8596058Abstract: There is provided a hydraulic system, including an oil tank storing operating oil, a hydraulic actuator, and a hydraulic pump which draws the operating oil from the oil tank and supplies the operating oil to the hydraulic actuator. The hydraulic system is provided with an operating oil separating unit which is located at a midway point of a main tube sending the operating oil from the hydraulic pump to the hydraulic actuator and which separates a part of the operating oil supplied from the hydraulic pump to return the part of the operating oil to the oil tank. A universal testing machine including the hydraulic system is also provided.Type: GrantFiled: November 7, 2011Date of Patent: December 3, 2013Assignee: Kokusai Keisokuki Kabushiki KaishaInventors: Sigeru Matsumoto, Hiroshi Miyashita, Kazuyoshi Tashiro, Kazuhiro Murauchi, Mitsuo Kakuta

Patent number: 8342202Abstract: A pipe coupling member for high-pressure fluid such as liquefied hydrogen includes a seal ring having a highly effective sealing function to prevent leakage of the fluid. The seal ring (72) is set in a seal ring setting space (39) defined by a second radial surface (36) and a seal ring setting surface (38) of a first tubular member (20), a forward end surface of a second tubular member (22), and the outer peripheral surface of a valve seat member (24). A forward end portion of the second tubular member (22) is provided with a communication hole (84) radially penetrating the forward end portion. The pressure of the high-pressure fluid on the downstream side of a valve seat surface (52) causes a fluid path in the second tubular member to be communicated with the sealing ring setting space (39) via the communication hole (84) and via a gap between the seal ring setting surface (38) and the outer peripheral surface of the forward end portion of the second tubular member.Type: GrantFiled: March 19, 2008Date of Patent: January 1, 2013Assignees: Nitto Kohki Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Takuya Nishio, Kunihiko Goto, Kazunori Aoki, Osamu Yamamoto, Kazuyoshi Tashiro, Goro Suzuki, Shinichi Nomura, Kosei Yoshida
